Apparently, episode 11 is airing in other countries. I've tried to summarize it a bit under the cut. This answers some of the questions like how Kat made it out of the bath tub alive!?
We left off with Roxie being kidnapped by Jamie.
Darryl is presumed dead.
Kat was passed out in the bathtub.
Joanna and Max were poisoned by Eleanor and locked in the basement.
The episode starts out with the three women hanging out together having a few drinks. Suddenly the girls notice that Kat's hair is wet. Then Joanna realizes that she can't move her arms. As Roxie reaches for a glass, it leaves a bloody hand print. The girls soon realize that what is happening is a dream. As they argue about who's dream it is, Jamie shows up to take Roxie away. They all wake up.
Roxie pleads with Jamie to let her go. Jamie tells her if she doesn't cooperate he will kill her. While Joanna thinks Max is unconscious, she pours her heart out to him. Of course Max hears every word. She tries to use her powers, but they don't work. Ray pulls Kat out of the bathtub. Kat tries to explain that she simply fell asleep after shortly getting into the tub around 6. To Kat's surprise Ray tells her it's now 9. She's been under water in the tub for a few hours.
Roxie and Jamie discover that Darryl's body is missing. Jamie becomes more and more agitated. He decides to take Roxie back to his apartment. When Penny shows up unexpectedly, Jamie hides Roxie in the bathroom. Jamie manages to get Penny out of the apartment before Roxie can be discovered.
Kat pays a visit to Eleanor's house to try to get a better understanding of her powers. Eleanor explains the reason why Kat didn't drown after being in the tub for hours is she's a witch and witches can't be drowned. If she continues to use her healing powers she will get more and more sick. Eleanor also explains that using her power to control the elements is slightly different than healing. People feel energized when they have strong emotions and for that reason Kat's control over nature won't make her suffer as her healing powers do.
Joanna uses her last bit of strength to throw things around with her mind so Kat knows she's in the basement. Eleanor and Kat fight. Eleanor has the power to control plants. Kat ultimately gets the upper hand and rescues Max and Joanna. Jamie leaves a message on Eleanor's machine. The girls realize something is up. Joanna uses her powers to make Max go home and forget about being locked in the basement.
Jamie drives Roxie out to the woods and digs a HUGE hole to bury her in. The girls go to the shop looking for Roxie and discover a bloody hand print. The hand print causes Joanna and Kat to flash back to their shared dream. In their dream they remember a sign, "Buck Hill Trail", and they realize that must be where Jamie has taken Roxie.
The girls race to the woods and manage to rescue Roxie. They knock Jamie into the hole that was meant for Roxie and bury him in it. The girls notice some rustling in the bushes and are fearful they were seen.
They show Max on the phone talking to an unknown person. He recounts what happened in the basement and we discover that Joanna's power didn't work on him because he had a special protective charm around his neck. He assures the anonymous person that he has everything under control with Joanna.
The last scene is of Jamie's hand coming out of the ground similar to the ending shot of the movie "Carrie".
Hopefully, the other unaired episode 13 will show up on the interwebs soon. :)
